I don't think it will wear out as quickly as the mfg thinks it will. I work as an instrument repair tech at a bio tech company. We have some 12v dc pumps that are rated to last for 1500 hrs. that have been on machines for over 5 years. These machines run almost 24/7/365 and pump some of the nastiest chemicals on the planet. We have more problems with seals going bad in the pump head than the motors burning out. And we just change the seals and reuse the pumps. I would have used one of these pumps for my water cooler but they only have 1/8 fittings and pump 5 to 30 mil a minute depending on the speed of the motor. One other problem with that pump is at full blast it draws 5 amps.
